I have loved the sparks between Charlie and Nora, much because it reminds me the dynamics between my husband and I, two independent adults that love each other so much that wouldn’t withhold the other from pursuing their own dreams. However I found the relationship between Nora and her sister a little troubled, Nora constantly mothering her and need to be up to date on everything that happens on her sister’s life showed how immature she was, nonetheless she grew through the book (her relationship with Charlie being of much help on this).
